AI InsightThe Cox regression analysis showed that a low fT3 was associated with long-termmortality [adjusted hazard ratio (HR)=2.00; 95% CI, 1.04–3.83; p=0.037] during the follow-up of mean 1.67 years.Conclusion: A low fT3 concentration was independently associated with CI-AKI and poor prognosis in elderly patients who had undergone PCI.(Anatol J Cardiol 2019; 21: 60-7)

Objective: Low free triiodothyronine (fT3) is common in elderly patients with cardiovascular disease. The purpose of this study was to evaluatethe relationship between low fT3 and contrast-induced acute kidney injury (CI-AKI), including the long-term outcomes, in elderly patients after apercutaneous coronary intervention (PCI).Methods: A total of 350 patients aged ≥75 years who underwent PCI between January 2012 and December 2015 were consecutively enrolled. Theperioperative thyroid function, including fT3, was measured before PCI. A low fT3 was defined as fT3 <3.1 pmol/L with normal thyrotropin and freethyroxine. CI-AKI was defined as an absolute serum creatinine (SCr) increase ≥0.30 mg/dL or a relative increase in SCr ≥50% from the baselinevalue within 48 hours after contrast media exposure. A multivariate logistic regression analysis was applied to analyze whether low fT3 was anindependent risk factor for CI-AKI. The Cox regression analysis was used to evaluate the relationship between low fT3 and long-term prognosis.Results: A total of 46 (13.1%) patients developed CI-AKI. The incidence of CI-AKI was significantly higher in the low fT3 group than in the normalgroup (26.5% vs. 9.9%, p<0.01). A multivariable logistic analysis demonstrated that a low fT3 level was significantly related to CI-AKI [odds ratio(OR)=2.41; 95% confidence interval (CI), 1.11–5.27; p=0.027]. The Cox regression analysis showed that a low fT3 was associated with long-termmortality [adjusted hazard ratio (HR)=2.00; 95% CI, 1.04–3.83; p=0.037] during the follow-up of mean 1.67 years.Conclusion: A low fT3 concentration was independently associated with CI-AKI and poor prognosis in elderly patients who had undergone PCI.(Anatol J Cardiol 2019; 21: 60-7)
